    Default HDMI output to 24 inch monitor

    Hey Guys,

    I have a HD set top box, but when i connect the HDMI output to the DVI input of my 24" monitor, it says it can't display the signal because the input is not 1920x1200 @ 60Hz? It is happy to display the signal when i select 575 or 720 output from the set top box, but when i select 1080 on the set top box the monitor wont display the picture?

    Why would this be? the Monitor is happy to upscale the image at 575 and 720 so why not 1080?

    At the moment i have connected the set top box to the monitor via composite cables but you can notice the difference when using the HDMI cable, even at 575 and 720.

    Is this the same for all set top boxes to a monitor that has a greater resolution than 1080?

    i think that the 1080i that's broadcasted is actually 1920x1088 as 1080 isn't a multiple of 16.

    what model monitor do you have and what model set top box?

    I have a Dell 24" Ultrasharp with a Homecast HD STB.

    what outputs are on your set top box? If it's 1080i, your monitor wont accept it over DVI. according to the monitors specs (im guessing you have the 2407 model or earlier, otherwise you'd be using hdmi->hdmi cable) it doesn't accept any interlaced signal over DVI:

    Video display capabilities (DVI playback) 480p/576p/720p/1080p (Supports HDCP)

    and of course all the standard vga/vesa resolutions which again - are all progressive.

    looks like you're out of luck. Just set it to 720p. the 2408 can accept the following inputs over HDMI:

    Video display capabilities (HDMI playback) 480i/480p/576i/576p/720p/1080i/1080p

    Now i understand, that really sucks......sort of defeats the purpose of using HD on the monitor now!

    Yeah its the 2407 so only have HDMI to DVI available (or composite etc but that means i have to convert to analogue).

    So i can play HD movies over the DVI cable but not free to air channels......why don't they broadcast 1080p? Bandwidth?

    Pretty disappointed now, as i only bought the monitor about 5 months ago....cheap too.

    Can HD STB's output a 1080i signal as 1080p?

    depends on the model. what is the exact model number of the set top box?

    I have a HT8000 Homecast PVR.

    I have noticed the 720p on the HDMI to DVI is better than the 1080i via composite cable. But the sides are cut off slightly for some reason (tends not to display image properly).

    I assume that if the STB could do 1080p out, even if the broadcast is 1080i it would convert and display via the HMDI to DVI better than 1080i via the composite cables?

    Doesn't the 2407 have component input? That might accept an interlaced signal and display it.

    As for the scaling, there's a few different scaling options that you can set in the monitor menus. I think you can choose to not scale at all and have some black pixels letterboxing the image, or to blow it up to the full hieght but lose some of the side edges.
